To all whom t may concern: f

Be it known that I,A VvTiLLis l. Narren, a citizen of the United States of America, residing at Decatur', in the county of Morgan and State of Alabama, `have invented certain new and useful Improvements inf` Processesfor Producing Rough-Texture Brick, of which the following is a specification. l

My invention relates ytoa new process for producing a novel rough texture" brick.V

Tlie*rug surface, which is produced by my process is an irregularly indented surstone in that it has spaced flattened surfaces of widely' varying outline standing in ref i lief from the mainbody of the brick and modified by traces of intersecting score lines.

I-eretofore, ithas been the'coinmonpractice rto produce rough texture by scoring the same Vwhen made from clay andfby wire cutting the same when made fromshale and the like.v Such bricks produce a very pleasing 'appearancev but arey characterized by a more or less regular succession of parallel ridges so that a ridged surface results which may if desired be more or less rolled, but the rolling does not'seriously affect the uniform grooved or ridged appearance of the finished face of the brick. The effectproduced by Vsuch bricks'is one vof symmetrical uniformity and heretofore it has not been possible to produce in brick Ythat pleasing irregular surface which may bestV be described as the surface obtained `from rotten stone.

I have discoveredvthat suchV a' sui'face can be obtained in either clay or shale brick in the following manner. The brick column, as it emerges fromr .the auger machine', is

scored longitudinally inthe usual manner.

both on its upper face and on either'or both side faces, this scoring being that necessary for producing lthe rough texture scored bricks above referred to.l The top face, and any other 'facevv desired, of the scored columns is then transversely scored, so as i' Vto produce intersecting score lines which ing my 4process into effect.

ridges lle'ft by thelongitudinal scores, has

a tendency-to break away and displace parts of such-ridges, and the ridge sections thus broken away are of varying v size andl are left in various positions, i. 'e.,are scattered indiscriminately, acrossthe face of tlielcolumn.

After the cross scoring operation the dou-y vble scoredy face of the column is passed under al roll as'tliermeans best suited to roll down and bond to the body ofthe column the loose particles of clay and theclaypatches left' between' the intersecting stavesfso that the yfinished column face will have offset-fiat tened portions formed by `irregular shaped clay vpatches rising in relief from the body of the column. Such aroughvtexturez face is very` similar to that existing in finished rotten stone blocks and affords ythe relief and irregularity in y*contourv and outline which'is very pleasingand attractive;

In the accompanying drawings, I Yhave illustrated in Fig. 1 a column of clay or .shale `in perspective associated' with mechanical scoringnand rolling jrdevices for carry- In F ig. 2 I illustrate fragmentally a brick with a rug face `produced by my process.

Similar reference numerals referto similar parts throughout the drawings.

According to the drawings, I have omitted lillustrating an auger mill from which the usual clay or shale column 2 is expelled and which is subjected to the action of top and side Scrapers 3 andA l to produce on the top and side faces of the column thelong'itudinal grooves `or scorings 5,such as are customary in vertical scored brick.

I illustrate atv 6' a transversel reciprocable scraper carrying points 7 which, in the carrying out of my process', are drawn back and forth across the top vface of the movingrcolumn, thus producing transverse scores 8 which intersect the longitudinal top scores v5 andstop just short of the corners of the column. This Vresults in breaking up the double scored face of the columnto such an extent that when it is subjected to the pressure 10 of the Aroller 9, .they raised displaced particles of clay are flattened down and bonded to the body. of the column, relative to which they constitute irregular relief surfaces 11 which give to the ,fa-ce of thef finished brick the rug surface conteniplated.

in Fig. e i show a emailed brick i2 hay- CII ing anend 13 with standardverticalscores 14 and having its face formed Withv raised portions 15 standing in relief relativetothe intervening depressedrsurfaces 16, the sur-l faces 15 and 16 lying generally indifferent planes and givingN the. finished faceV of the brick the novel appearance Which is char acteristic of my invention. lt-v Wil-l be observed that in this finished face of the brick are to be seen traces of both the longitudinal and transverse scoring which' serve to make more irregular the rough :texture of the face of the brick.

The roller 9 has the usualfabric cover 'i7 to prevent clay sticking to it and to give the rolled relief surfaces 15 of the brick a rough and not a. glazed appearance.

My invention contemplates the scoring of the face of the brick being accomplished by manual tool or mechanical apparatus suitable to provide intersecting core. lines running lengthwise andl transverse-ly ofv the column, and in a'companion'application of even date herewith I' have describedV and claimed what I regard as the preferred mechanism for the-carrying out of .my present process.

rThough I have described with great particularity the details ofthe embodiment of the-invention herein shown, it is not to be construed that l am limited' thereto, as changes in arrangement and substitution or equivalent steps may be madel by those skilled in the art Without departing from theY invention as defined in the appended claims.

Having thus described my invention, What I claim as n eW and desirevto secure by Letters Patent, is :-V

1. The hereindescribed process for the production of'a rough texture brick, which consists in breaking-up the face of the brier column by intersecting score lines into irregularly disposed raised patches of the column material, rolling these raised patches to flatten them, and cutting .the column into bricks.

2. The hereindescribed process for the production of a rough texture brick, Which consists in irst longitudinally scoring the top .surface of a clay or shale column, then transversely scoring the scored top surface of said column except its marginal edges7 then rolling such transversely scored surface, and then cutting the column into bricks. v

The liereindescribed process for the production of a rough texture -brick which consists in lirst longitudinally scoring the top surface of al clay or shale` column, then transversely scoring said scored top surface between lines slightly spaced from the corner edges of the column, then rolling such transversely scored surface with a fabric covered roll, and then cutting the column into bricks.

In testimony whereof I alfiX my signature.
